14. 參考 MS VB.COMPATIBILITY

17. 需要三個 dll 檔案

18. 透過參考加入 dll

20. 讀卡號

21. Imports VB = Microsoft.VisualBasic Imports GIGATMS.NF.MifareReader Imports GIGATMS.NF.GNetPlus ‘ 宣告全域變數 ‘ 建立物件 mf5x1 Public WithEvents MF5x1 As New GIGATMS.NF.MifareReader ‘ 卡號 Public Id As Integer

22. 透過 mf5x1 物件讀取卡號 Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click MF5x1.mfRequest() ' 對機器發出命令要求讀取 ' 讀取卡號 Id = MF5x1.mfAnticollision If Id <> 0 Then Select Case MF5x1.mfCurrentClass Case iCardTypeConstants.MIFARE_UltraLight, iCardTypeConstants.MIFARE_DESFire TextBox1.Text = VB.Left(Id.ToString("X").PadLeft(8, "0"), 6) Case Else TextBox1.Text = Id.ToString("X").PadLeft(8, "0") End Select Else TextBox1.Text = MF5x1.GNetErrorCodeStr End If End Sub

23. 執行結果 出了甚麼問題？

24. Port 需要啟動 Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load MF5x1.CommPort = 12 MF5x1.Settings = "19200,n,8,1" MF5x1.PortOpen = True End Sub

25. 判斷卡片種類 Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim nResult As Short MF5x1.mfRequest() ' 對機器發出命令要求讀取 ' 讀取卡號 Id = MF5x1.mfAnticollision If Id <> 0 Then Select Case MF5x1.mfCurrentClass Case iCardTypeConstants.MIFARE_UltraLight, iCardTypeConstants.MIFARE_DESFire TextBox1.Text = VB.Left(Id.ToString("X").PadLeft(8, "0"), 6) Case Else TextBox1.Text = Id.ToString("X").PadLeft(8, "0") End Select Else TextBox1.Text = MF5x1.GNetErrorCodeStr End If ' 判斷卡片的記憶體大小 nResult = MF5x1.mfSelectCard(Id) If nResult > 0 Then Select Case MF5x1.mfCurrentClass Case iCardTypeConstants.MIFARE_UltraLight, iCardTypeConstants.MIFARE_DESFire Label2.Text = "MIFARE_UltraLight" Case iCardTypeConstants.MIFARE_1K Label2.Text = "MIFARE_1K" Case iCardTypeConstants.MIFARE_4K Label2.Text = "MIFARE_4K" End Select End If End Sub

26. 讀取資料 BUTTON2.ENABLED=0 等 BUTTON1 確定 讀到卡號才啟動 BUTTON2 SECTOR:0-15 BLOCK:0-3

27. 讀取資料 Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click Dim szKey As String Dim bResult As Boolean ' 認證結果 Dim bBuffer() As Byte Dim sResult As String szKey = vbNullString ' 表示使用機器上與卡片上的 KEY 進行認證 If RadioButton1.Checked Then bResult = MF5x1.mfAuthenticate(ComboBox1.SelectedIndex, bKeyTypeConstants.KEY_A, vbNullString) Else bResult = MF5x1.mfAuthenticate(ComboBox1.SelectedIndex, bKeyTypeConstants.KEY_B, vbNullString) End If

28. 讀取資料 If bResult Then Label9.Text = "Pass" Button3.Enabled = True ' 讀取資料 ReDim bBuffer(0 To 15) If MF5x1.mfRead(ComboBox2.Text, bBuffer) Then sResult = pcr310_fun.BytesToHex(bBuffer) If MF5x1.mfCurrentClass = iCardTypeConstants.MIFARE_UltraLight Then Label8.Text = Mid(sResult, 0, 16) Else Label8.Text = sResult End If TextBox3.Text = tostring1(Label8.Text) Else Label9.Text = MF5x1.GNetErrorCodeStr TextBox3.Text=“” Button3.Enabled = False Exit Sub End If End Sub

29. Private m_bNoChangeEvent As Boolean Function tostring1(ByVal a As String) If m_bNoChangeEvent = False Then m_bNoChangeEvent = True Dim arr(a.Length) As Byte arr = pcr310_fun.HexToBytes(a) Dim i As Integer = 0 Dim temp As String = "" Dim x As Byte x = 161 ' 判斷是不是繁體字 0xA1 For i = 0 To arr.Length - 1 Step i + 1 If arr(i) > x Then temp = temp + System.Text.Encoding.GetEncoding("Big5").GetString(arr, i, 2) i = i + 1 Else i = arr.Length ' 直接結束 End If Next m_bNoChangeEvent = False If arr(0) > x And arr.Length <> 0 Then Return (temp) Else Return (pcr310_fun.HexToString(a)) End If End Function

31. 寫入資料 BUTTON3

33. Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click Dim BlkNum As Short Dim bResult As Boolean ' 認證結果 Dim st1 As Integer Dim bBuffer() As Byte Dim key As String Dim a1 As String If RadioButton1.Checked = True Then key = bKeyTypeConstants.KEY_A ElseIf RadioButton2.Checked = True Then key = bKeyTypeConstants.KEY_B End If ' 讀取使用者選擇的 SECTOR st1 = ComboBox1.Text

34. 'ABkey 認證 bResult = MF5x1.mfAuthenticate(st1, key, vbNullString) If bResult Then Else MessageBox.Show(MF5x1.GNetErrorCodeStr) Exit Sub End If ' 讀取使用者選擇的 BLOCK BlkNum = ComboBox2.Text ' 將資料轉 16 進制 a1 = VB.Left(pcr310_fun.StringToHex(TextBox3.Text) & New String("0", 32), 32) bBuffer = pcr310_fun.HexToBytes(a1) ' 寫入資料 If MF5x1.mfWrite(BlkNum, bBuffer) Then MessageBox.Show(" 寫入成功 ") Else MessageBox.Show(" 寫入失敗 ") End If End Sub

36. 存入選擇的 Sector( 機器上 ) Imports GIGATMS.NF Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim res As Boolean Dim nSector As Short ' fill to 12 char (6 HEXs) TextBox1.Text = TextBox1.Text & New String("0", 12 - Len(TextBox1.Text)) nSector = ComboBox1.SelectedIndex 'Save Key To EEPROM for one sector With Form1 If RadioButton1.Checked Then ' Key Type A res =.MF5x1.mfSaveKey(nSector, MifareReader.bKeyTypeConstants.KEY_A, TextBox1.Text) Else ' Key Type B res =.MF5x1.mfSaveKey(nSector, MifareReader.bKeyTypeConstants.KEY_B, TextBox1.Text) End If If res Then ' show status Label1.Text = "Save Key To EEPROM:OK(" & CStr(nSector) & ")" Else Label1.Text = "Save Key To EEPROM:NG(" & CStr(nSector) & ")" End If End With End Sub

37. 存入所有 Sector( 機器上 ) Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click Dim res As Boolean Dim nSector As Short ' Save Key To EEPROM for all sector ' szKey = TextBox1.Text With Form1 For nSector = 0 To ComboBox1.Items.Count - 1 ' for MIFARE 1K (total 16 sectors) For retry = 1 To 3 If RadioButton1.Checked Then ' Key Type A res =.MF5x1.mfSaveKey(nSector, MifareReader.bKeyTypeConstants.KEY_A, TextBox1.Text) Else ' Key Type B res =.MF5x1.mfSaveKey(nSector, MifareReader.bKeyTypeConstants.KEY_B, TextBox1.Text) End If If res Then ' show status Label1.Text = "Save Key To EEPROM:OK(" & CStr(nSector) & ")" Exit For Else Label1.Text = "Save Key To EEPROM:NG(" & CStr(nSector) & ")" End If Next retry Next nSector End With End Sub

38. 改變任一個 READER 上 sector 的 KEY 試試是否可以讀取資料？

39. 存 KEY 入 TAG 卡片要先通過認證，才能執行動作

40. Private CB3, CB1, CB0, CB2 As Short Private Sub Button5_Click_1(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button5.Click CB0 = 0 CB1 = 0 CB2 = 0 CB3 = 4 TextBox2.Text = TextBox2.Text & New String("0", 12 - Len(TextBox2.Text)) TextBox4.Text = TextBox4.Text & New String("0", 12 - Len(TextBox4.Text)) Label12.Text = vbNullString If MF5x1.mfAccessCondition(TextBox2.Text, TextBox4.Text, CB0, CB1, CB2, CB3) Then Label12.Text = "OK" Else If MF5x1.GNetErrorCode = 0 Then Label12.Text = "NG" Else Label12.Text = "NG(" & MF5x1.GNetErrorCodeStr & ")" End If End Sub
